Top installation of steel structure workshop

1, the top installation of the steel structure workshop is usually placed on the roof of the gutter (color steel or stainless steel), forming a gutter. The distance between the eaves and the column distance is taken, that is, the eaves are part of the main frame, and the eaves are connected by C-type steel purlin. The coating that has made up cannot deposit too long, coating needs to be made up that day. The use of thickener should follow the instructions and not be added randomly.

2, steel structure workshop top coating environmental measurement and absolute humidity should meet the requirements of coating product specification, when the product specification does not require, environmental measurement can be between 5 and 38℃, absolute humidity can not be more than 85%. There should be no condensation during painting. Cover from rain within 4 hours after painting. The parts that are not coated as shown in the steel structure installation drawing should not be coated. The welding seam and high-strength bolt joint are temporarily not coated. After the on-site construction, the welding seam and high-strength bolt joint shall be filled with anticorrosive paint.

3. The roof column of the steel structure workshop is installed on the top to bear the vertical load and wind load of the light wall transmitted by the C-type steel wall beam, and the roof beam mainly bears the load of the gutter water or snow load. The section of eave components (eave column, eave beam) is generally made of rolled I-steel or high-frequency H-beam, and the section size is determined by the calculation of bearing capacity. The eave column and the eave beam are shown as a whole, and the end and the frame column are fixedly connected, that is, calculated as a cantilever member. Under normal circumstances, the load borne by the eaves of steel structure workshop is small, and the section of 200 high frequency welding H beam is generally choosed.
